### What 3 things determine the exposure of a photograph?

• A.

Aperture, f-stops, timer mode

• B.

Shutter speed, ISO, metering mode

• C.

Aperture, shutter speed, ISO

• D.

F-stop, aperture, depth of field

C. Aperture, shutter speed, ISO
Explanation
The exposure of a photograph is determined by three factors: aperture, shutter speed, and ISO. Aperture refers to the size of the opening in the lens that allows light to enter the camera. Shutter speed determines the length of time that the camera's shutter remains open, controlling the amount of light that reaches the camera sensor. ISO measures the sensitivity of the camera sensor to light. By adjusting these three settings, photographers can control the amount of light that enters the camera and achieve the desired exposure for their photographs.

### You’re taking a picture of your dog, Fred jumping to catch a frisbee. Which of these shutter speeds would best freeze the action?

• A.

1 second

• B.

1/500th

• C.

1/4 second

• D.

1/60th of a second

B. 1/500th
Explanation
A shutter speed of 1/500th of a second would best freeze the action of Fred jumping to catch a frisbee. This is because 1/500th of a second is a very fast shutter speed, allowing the camera to capture a very short duration of time. With such a fast shutter speed, the image will be sharp and freeze the motion of Fred in mid-air, giving the impression that he is suspended in the air while catching the frisbee.

### You’re taking a picture of a landscape. Which aperture would be best for getting all of it in focus?

• A.

F8

• B.

F22

• C.

F2.8

• D.

F16

B. F22
Explanation
A smaller aperture, such as f22, would be best for getting all of the landscape in focus. Smaller apertures result in a larger depth of field, meaning that more of the scene will be in focus from the foreground to the background. This is particularly useful for landscapes where you want to capture as much detail as possible and have everything from the closest objects to the distant horizon in sharp focus.

### Compared to f/8, f/16 is:

• A.

A smaller opening

• B.

Farther away

• C.

A larger opening

• D.

Blurrier

A. A smaller opening
Explanation
The f-number represents the size of the aperture opening in a camera lens. A smaller f-number indicates a larger opening, allowing more light to enter the camera. Conversely, a larger f-number represents a smaller opening, allowing less light to enter the camera. Therefore, f/16 is a smaller opening compared to f/8.

### Out of the apertures listed, which will give you the most light?

• A.

F22

• B.

F5.6

• C.

F2.8

• D.

F11

C. F2.8
Explanation
The aperture controls the amount of light that enters the camera. A smaller aperture number indicates a larger opening, allowing more light to pass through. In this case, f2.8 has the smallest aperture number, meaning it will allow the most light to enter the camera compared to the other options listed (f22, f5.6, f11).

### Which aperture will give you the most blurry background?

• A.

F22

• B.

F16

• C.

F2.8

• D.

F11

C. F2.8
Explanation
A larger aperture (smaller f-number) allows more light to enter the camera, resulting in a shallower depth of field. This means that when shooting at f2.8, the background will be more out of focus and blurry compared to shooting at f22, f16, or f11.

### Choose between the following: Fast / slow shutter speeds are good for 'freezing' sports and action photography.

Fast
Explanation
Fast shutter speeds are good for 'freezing' sports and action photography because they allow the camera to capture a quick moment in time without any motion blur. When shooting fast-moving subjects, such as athletes or wildlife, a fast shutter speed will ensure that the image is sharp and clear, freezing the action in place. This is particularly important in sports photography to capture fast-paced moments like a basketball player mid-air or a soccer player kicking the ball. A fast shutter speed also helps to capture details in fast-moving subjects, making it easier to capture the decisive moment.

### Fill in the missing gap in the following sentence: If you hand hold a camera at below  .......... sec you will get what is known as camera shake in your images.

60th
60
1/60th
1/60
Explanation
If you hand hold a camera at below 1/60th of a second, you will get what is known as camera shake in your images. This means that if the shutter speed is slower than 1/60th of a second, the camera will not be able to capture a sharp image because any movement of the camera or subject will result in blurriness. Therefore, it is important to use a faster shutter speed or a tripod to avoid camera shake and ensure clear images.
